Spending 'Fake Money'

About a year ago, after a night of gin and tonics, he said he ended up on iTunes, hitting the "purchase" button over... and over... and over again.

"I just stopped thinking about what I was spending and started thinking about how much fun it would be to own all these albums," said Cummins, who will star in a Comedy Central special later his month. "The next day I was like, 'Dear God, that could be a real problem.'"

The damage wasn't too severe. Cummins, who said he's normally a one album kind of guy, ended up with about $100 worth of (or 10) albums.

And it inspired a comedy bit that he said always seems to be popular with crowds.

"It is definitely not just me. There's definitely always somebody in the audience that gets it more than the rest of the people," he said. "[There's] recognition laughter."

Drinking and shopping are both fun on their own, but aside from the fun factor he said it doesn't feel like real when you're a few cocktails in.

"That's the allure of the online shopping," he said. "You're not worried about money. ...It doesn't seem like you're spending money. It's like fake money."

Not All Tipsy Transactions Are Final

But some beer-guzzling buyers have learned that not all online purchases and bids are set in stone.

During the "Johnny Cash" phase of his college years, J.P Hester, a 25-year-old from Gainesville, Georgia, said he came home after a long night out and started clicking around on his computer.

He woke up in the morning and got a shock when he checked his e-mail and found a message reading, "Congratulations, you have won the Johnny Cash cuff links," he said."It was like $300 or something."

Thinking his new eBay acquisitions had once been owned by the Man in Black himself, he didn't panic too much at first. But when he realized that they were only cuff links with Cash's picture on them, he scrambled to e-mail the seller.

"I got the guy's name and e-mail and told him my story of how I was a poor college kid and was just blacked out," he said. "Luckily enough, he just laughed about it and said, 'I was really wondering why somebody paid so much for these.'"

What Happens When Ambien Meets eBay?

And then there are variations on the theme.

Marni, a 30-year-old from New York, said that, about four years ago, after seeing a Dyson vacuum cleaner at a friend's house, she was determined to have one of her own.

"I stalked Dysons on eBay for a while, but anytime the price was near reasonable, I was outbid at the very last second," she said.

But one night, after taking an Ambien to fight insomnia, she said she must have gotten too bold before bedtime.
